Forest of giants Recovery effect not working

With the card set equip or not, my F1 items and %hp potion recover the same HP. Using Cursed Doll engraving.

Well i have the same set up and your 45% + 15% from the card is 60 - 25 from cursed doll.
So your potion will heal 35% if ur using the 45% one.

Re-equip it and now it worked, dont know what’s wrong

Ah it not works in chaos gates
